First Claim
1. A wireless audio system, comprising:
- a primary wireless transceiver comprising;
a first radio frequency (RF) module configured to receive, from an audio source, first audio information at a first frequency; and
a second RF module operatively coupled to the first RF module and configured to transmit second audio information at a second frequency lower than the first frequency, the second audio information generated based on the first audio information; and
a secondary wireless transceiver comprising;
a third RF module configured to receive, from the second RF module of the primary wireless transceiver, the second audio information at the second frequency; and
a fourth RF module configured to (i) receive, from the audio source, the first audio information at the first frequency, and (ii) be disabled when the third RF module receives the second audio information from the second RF module of the primary wireless transceiver,wherein each of the first and fourth RF modules implements a first short-range wireless communication protocol, and each of the second and third RF modules implements a second short-range wireless communication protocol amended from the first short-range wireless communication protocol; and
the primary wireless transceiver further comprises a physical layer module shared by the first RF module and the second RF module and configured to generate a first physical link between the audio source and the first RF module based on the first short-range wireless communication protocol and generate a second physical link between the second RF module and the third RF module based on the second short-range wireless communication protocol.

Abstract
Embodiments of wireless audio systems, wireless transceivers, and methods for wirelessly communicating audio information are disclosed herein. In one example, a wireless audio system includes a primary wireless transceiver and a secondary wireless transceiver. The primary wireless transceiver includes a first radio frequency (RF) module configured to receive, from an audio source, first audio information at a first frequency. The primary wireless transceiver further includes a second RF module configured to transmit second audio information at a second frequency lower than the first frequency. The second audio information is generated based on the first audio information. The secondary wireless transceiver includes a third RF module configured to receive, from the second RF module, the second audio information at the second frequency. The first RF module implements a first short-range wireless communication protocol. Each of the second and third RF modules implements a second short-range wireless communication protocol amended from the first short-range wireless communication protocol.

17. A method for wirelessly communicating audio information, comprising:
-
generating, by a physical layer module, a first physical link between an audio source and a first RF module based on BLUETOOTH protocol; receiving, from the audio source via the first physical link, first audio information at a first frequency for BLUETOOTH communication using the BLUETOOTH protocol; presenting at least part of the first audio information; generating second audio information based on the first audio information; generating, by the physical layer module, a second physical link between a second RF module and a wireless transceiver based on amended BLUETOOTH protocol, wherein the physical layer module is shared by the first RF module and the second RF module; and transmit, to the wireless transceiver via the second physical link, the second audio information at a second frequency lower than the first frequency for near-field magnetic induction (NFMI) communication using the amended BLUETOOTH. - View Dependent Claims (18, 19, 20)
